IMPROVEMENT IN WHEEL PLCWS. Q

Specification forming part of Letters Patent No. 122,442, dated January2, 1872.

SPECIFICATION.

I, WILLIAM G. OnossLEY, of Apple River, in the county of J o Daviess andState of Illinois, have invented an Improved Gang-Plow, of which thefollowing is a specification:

The present invention relates to an improvement on a combined sulkyplowand cultivator patented by me January 7, 1868; and its nature consistsin the novel construction and combination of the devices hereinafterdescribed and claimed.

In the drawing, Figure 1 is a longitudinal sectional elevation of myimproved gan g-plow; Fig. 2, a plan or top view of the beams and theirattachments; Fig. 3, a view of thefront' ends of the beams and theattachments which hold them in place when the plows are in opera-tion.

A B B B represent a framework, which is similar in construction to thepatent referred to, and mounted on wheels Q in substantially the samemanner, viz., by means of rackand pinion-framesg h, operated by leversb. Nothing new is therefore claimed in their regard.

In the present invention the plow-beams O D are made to have asimultaneous movement by means of short tie-beams F G, which are held intheir respectiveplaces by means of screws or bolts j, ,Fig. 1, so thatany tilting of either beam will give the other beam a correspondingmovement, and, consequently, elevate or depress the plows E E equally.This arrangement is important, inasmuch as the beams are now controlledby a single lifting -1 and 4, and are thus brought down, so as to lowerthe draft and cause the plows to draw into the ground properly, and toovercome the tendency the plows have to raise up behind.This-arrangement is important, inasmuch as th'eplows are made to runvery steadily and hold to their work so as to cut furrows of uniformdepth without any unusual care on the part of the operator. The plowalso operates with less strain on its several parts.- Another advantageconsists in the-position of the pivotplates N, Figs. 1 and 4, which areplaced on the under sides of the beams, and, consequently, cannotreadily get loose, inasmuch as the beams rest thereon. These dependingstandards M are rigidly attached to plates L L, which are bolted to therear side of the frame-piece B, several holes being made in said plates,so that theymay have any adjustment necessary to throw the plows .E toor from the land. The forward en ds of the beams are held in a fixedposition when the plows are in operation by means of depending standardsJ J, which are rigidly fastened to plates K, secured to the middle framepiece B by bolts or otherwise, as most convenient. These standardsproject down onto the sides of the beams a little distance; and betweenthem are secured short bars n a, Fig. 3, against which the plates P P,same figure, hear when the beams are in position, as shown at Fig. 1. Bythis means the beams are preventedfrom swing-- ing on the joints It,while at the same time the beams always have the same working position.

The device for raising and lowering the by dotted lines Z, the beams G Dwill be raised up,- a notch, d, in the back partof 0 being used to holdthe lever Z in a fixed position when the plows are to be carried to orfrom a field. To hold the standards M firmly in place braces I areattached to them at R and fastened to the under sides of the plates K,thus keeping all of the parts firm as against the draft of the theplows. By placing the operating devices U Z cin front of the driversseat 10 the lever T is always in reach of the driver and adjacent to thelevers b, which raise and lower the framework.

Having thus described the construction and operation of my invention,What I claim, and desire to secure by Letters Patent of the UnitedStates, is-

The combination of the oentrallyadjustable guides M M with the dependinglaterally-adjustable standard J J, said standard being arranged to holdthe forward ends of the beams O D in position when elevated, and leavingthe same free when the plows are elevated, as set forth and shown.
